On the probabilistic min spanning tree Problem [PDF]

open access: yes, 2010
International audienceWe study a probabilistic optimization model for min spanning tree, where any vertex v i of the input-graph G(V, E) has some presence probability p i in the final instance G′ ⊂ G that will effectively be optimized.

On the Longest Spanning Tree with Neighborhoods [PDF]

open access: yesDiscrete Mathematics, Algorithms and Applications, 2018
We study a maximization problem for geometric network design. Given a set of [Formula: see text] compact neighborhoods in [Formula: see text], select a point in each neighborhood, so that the longest spanning tree on these points (as vertices) has maximum length. Here, we give an approximation algorithm with ratio [Formula: see text], which represents

Generalized minimum spanning tree games

open access: yesEURO Journal on Computational Optimization, 2016
The minimum-cost spanning tree game is a special class of cooperative games defined on a graph with a set of vertices and a set of edges, where each player owns a vertex. Solutions of the game represent ways to distribute the total cost of a minimum-cost

Breaking intractability of spanning caterpillar tree problem: A logical approach [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2022
In this paper we pursue a logical approach to prove that the optimisation problem of finding a spanning caterpillar tree in a graph has polynomial algorithm for bounded tree width graphs.

Spanning Trees—Short or Small [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 1996
We study the problem of finding small trees. Classical network design problems are considered with the additional constraint that only a specified number $k$ of nodes are required to be connected in the solution. A prototypical example is the $k$MST problem in which we require a tree of minimum weight spanning at least $k$ nodes in an edge-weighted ...

MENCARI MINIMUM SPANNING TREE DENGAN KONSTREN

open access: yesJurnal Matematika UNAND, 2019
Misalkan G = (V, E) adalah graf tak berarah terhubung yang bukan tree, berarti di G terdapat cycle. Dengan cyclic interchange maka diperoleh subgraf T yang tidak memuat cycle. Subgraf T inilah yang dinamakan dengan spanning tree.

Linking and Cutting Spanning Trees [PDF]

open access: yesAlgorithms, 2018
We consider the problem of uniformly generating a spanning tree for an undirected connected graph. This process is useful for computing statistics, namely for phylogenetic trees. We describe a Markov chain for producing these trees. For cycle graphs, we prove that this approach significantly outperforms existing algorithms.

Determining hop-constrained spanning trees with repetitive heuristics

open access: yesJournal of Telecommunications and Information Technology, 2023
The hop-constrained minimum spanning tree problem is the problem of determining a rooted spanning tree of minimum cost in which each path from the root node to any other node contains at most H hops or edges.
